  • F0-a Average of three replicates. se = 0.7 nmol min−1mg−1protein.

  • F0-b Days after flowering.

  • F0-c Reproductive leaf is the leaf next to a seed pod and is staged relative to flowering.

  • F0-d Young leaf is the first true leaf of 14-d-old plants.

  • F0-e Mature leaf is the first true leaf of 30-d-old plants, before flowering.
